An extension for your browser can enhance your online experience in several ways. Translations, conversions, spellchecking, shopping, and blocking popup ads are some of the services they can assist you with. You can customize your browsing experience using these extensions, and you may even be able to alter the way websites are displayed. There are several popular extensions available for Chrome, but the dark mode is an example.
It is imperative to remember that not all extensions are safe. By giving them access to such information, such as your personal information, you are giving them a lot of power.
Although some extensions store this data for convenience, others use it to track you or launch a cyberattack against your computer. A malicious Chrome extension was recently reported to have been downloaded 1.4 million times since it first appeared on our site.
The cybersecurity firm Guardio Labs reports that a newly discovered malicious advertising campaign has been discovered in which Chrome extensions are used to hijack web searches and embed affiliate links into any other websites you visit.
The company's security researchers have dubbed this advertising campaign "Dormant Colors" since all of the malicious extensions in question offer color customization options for Chrome, which makes them the right candidate for being dubbed a malicious advertising campaign. However, the extensions themselves do not include malicious code when installed. This is how they were able to bypass Google’s security checks and end up on the Chrome Web Store in the first place.
Extensions for Google Chrome - Dormant Colors
Following a thorough investigation into this matter by Guardiothis campaign use ad, it was found that there were thirty different versions of these malicious browser extensions available on both the Chrome and Edge web stores with more than a million installations altogether.

• Action Colors

Explanation of how to remove Chrome extensions manually
There are several malicious extensions listed below that have since been removed, but you may need to manually remove them by clicking on the three dots menu at the top right-hand corner of your Chrome browser to remove them permanently. Upon clicking 'More', you will be taken to the More tools section where you will be able to access Extensions.
Making money by hijacking your browser to make money from clicks on the ads
The cybercriminals behind this campaign use ads and redirects to trick unsuspecting users into installing their malicious extensions. This is done when they visit sites that offer the opportunity to play videos or download files. This is done so that they can then go one step further and download malicious extensions.
There are two sites where you can watch videos or download programs. However, when you click the videos or download programs link, you are redirected to another site that requires you to add an extension before you can continue. It is quite likely that you will be prompted to install a color-changing extension when you click either the 'OK' button or the 'Continue' button. This extension initially seems harmless on the surface.
The problem with these extensions is that once installed, their purpose is to redirect users to pages that redirect them to malicious scripts that side-load malicious scripts that show how to perform search hijacking for the extensions, but also that tell the extensions what sites affiliate links can be inserted on to generate affiliate revenue. The creator of these malicious extensions earns a lot of money from these advertisements, which are sold to third parties for profit, which is known as search data.
It is also possible to use these Dormant Colors extensions for automatic redirects to the same page with affiliate links added to the URL of each page instead of redirecting users to an entirely different page. Whenever anyone purchases an extension on any of these sites, the developers of such an extension will receive a commission for their work.
Guardia, in a blog post, tells that the malicious extension campaign may have the potential to spread further over the coming weeks. "As this campaign continues to run, it is shifting domains, generating a wide assortment of extensions, and re-inventing several color-and-style-changing functions you are sure to be able to do without."
It is also worth mentioning that the code injection technique analyzed here provides the mitigation and evasion measures necessary to contribute to further malicious activities in the future, especially since it is a huge infrastructure for mitigation and evasion.
The most effective way to keep your browser from getting infected by malicious extensions
The most appropriate time to make sure you have an effective antivirus solution installed on your laptop or PC is before you add any additions to your browser, especially if you plan on adding any new extensions to it. In this way, you will be able to protect yourself against malware infection or having your personal information stolen and misused.
Additionally, when you install any extensions, be sure to only use trusted sources, such as the Chrome Web Store or the Microsoft Edge Add-ons store, as these are both reliable sources. The fact that malicious extensions do slip through the cracks from time to time does not change the fact that you are still safer when you install browser extensions from an official store rather than from the web.
Additionally, you should always ask yourself whether or not you need an extension before downloading it. Do you need it, or do you just want to use it? When you come across an extension that seems too good to be true, then you can be certain that it is and is not worth downloading. In addition to checking the extensions in your browser regularly, you might also want to consider adding new ones.
You need to regularly take a look at the extensions you have installed in your browser and make sure they are still relevant. Delete any of these that you no longer need. Also, keep an eye out for any new ones you may not have noticed you have added without your knowledge. Using browser extensions, you can add all kinds of new features and options to your browser that are not available in its built-in functionality.
